87 350 TBI camshaft options

[bigblue87]

Was woundering if anyone knows or had allready researched this. I"ve ended up having to rip my motor apart and replace a bad cam. Thought about throwing a little bit bigger cam in it but im not sure how big i can go before i start having to mess with the computer and other things. i was also planning on taking the heads in to be reworked.

Also, i went through and seen a million threads about headers.... So whats the general consensus for a decent headers?
